Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ عَنِ الْأَعْمَشِ عَنْ عُمَارَةَ بْنِ عُمَيْرٍ عَنْ يَحْيَى بْنِ الجَزَّارِ عَنْ عَائِشَةَ قَالَتْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُوتِرُ بِتِسْعٍ فَلَمَّا أَسَنَّ وَثَقُلَ أَوْتَرَ بِسَبْعٍ.

Muhammad b. Fudayl told us, from al-A'mash, from Umarah b. Umayr, from Yahya b. al-Jazzar, from Aishah, who said: The Messenger of Allah (peace and blessings be upon him) used to pray Witr with nine rak'ahs; then when he grew old and became heavy with age, he prayed Witr with seven.
